CATTLE-GUARD.

Application filed September 29, 1914.

To all whom it may concern:

Be it known that l, FERNAND A. STIEVEN- ARD, citizen of France, residingat Grand Forks, in the Province of British Columbia, Dominion of Canada,have invented certain new and useful Improvements in Cattle- Guards; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to new and useful improvements in cattle guards forrailway tracks and has for its primary object to provide a guard thatwill when the cattle attempt to cross or walk down the track be operatedautomatically by the cattle engaging a certain part of the guard. sothat a barrier is formed and the cattle prevented walking on the tracks.

Another object of importance is to provide a device of the characterdescribed which employs means whereby the barrier is caused to rise fromdown position quickly so as to frighten the cattle and cause them tomove away from the track.

Another object is to' generally improve and simplify cattle guards ofthe character described so as to render them more practical, reliableand efficient in operation and inexpensive to manufacture and install.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claim.

With reference to the drawings wherein I have illustrated the preferredembodiment of my invention as it is reduced to practice, and throughoutthe several views of which similar reference numerals designatecorresponding parts, Figure 1 is a top plan view of my improved guard,Fig. 2 is a side elevation showing the guard in up position, Fig. 3 is atransverse sectional view taken on line 3-3 of Fig. 1 showing auxiliaryguards on opposite sides of the rails as well as between the rails andthe end of a fence, and Fig. 4: is an enlarged detail sectional viewshowing the sliding pivot arrangement for the guard.

Referring to the drawings by characters of reference, the numeral 1designates the rails of a track and 2 the ties thereof. Pivoted betweenthe rails 1 is a barrier or guard Specification of Letters Patent.

member 3 that consists of a plurality of spaced parallel strips 4 thathave interposed at the pivoted ends of the barrier spacing blocks 5 thatare secured to the strips 4. shaft or pivot rod 6 is extended throughthe blocks 5 and strips i and projected beyond the outermost strips 4.Carried on the outer ends of the rod or shaft 6 are enlarged slideblocks 7 that are pivotally arranged upon the shaft 6. The blocks 7 areslidably mounted within longitudinal slots formed in guide blocks 8which are secured upon one of the ties 2 of the track and are mountedinside of the rails 1. It will thus be seen that the member 3 isslidably and pivotally mounted.

Pivotally mounted between the rails 1 is an operating element designated9 as an entirety that consists of a plurality of spaced strips 10 withblocks 11 secured between the pivoted ends thereof. A foot plate 12 issecured upon the pivoted end of the operating element 9 upon the blocks11 and is of sufficient width to insure the cattle stepping thereuponwhen the cattle attempt to walk upon. or cross the track. A pivot rod orshaft 13 is inserted transversely through the strips 10 of the element 9at a point adjacent to the end to which the blocks 11 are secured butintermediate the ends of the strips and is pivotally journaled inupstanding bearings 14 carried by one of the adjacent ties 2. The otherends of the strips 10 composing the member 9 are disposed between thestrips 1 and wear blocks 15.that are arranged between the strips i bymeans of a pivot rod 16 that is inserted transversely through the strips4: and 10, also wear blocks 15 and has suitable nuts 1'? turned on itsfree end to prevent derangement thereof. The ends of the strips 10 areconnected with the strips 1 at a point intermediate the ends of thestrips 4 thus when the foot plate 12 is en gaged by the cattle anddepressed the opposite end of the member 9 will be moved upwardly andpull the guard 3 into up position as shown in Fig. 2 thus preventingcattle passing by the guard and at the same time frightening the cattleso that they will run from the guard off of the track.

If desired, the guard may be placed on either side of the track as shownin Fig. 3 as well as in the middle.

With reference to the foregoing description and accompanying drawings,it will be readily seen that I have provided a cattle guard which Willprove eflicient in use and may be easily installed and manufactured.

In practice, I have found that the form of my invention, illustrated inthe drawings and referred to in the above description, as the preferredembodiment, is the most eflicient andpractical; yet realizing that theconditions concurrent with the adoption of my device will necessarilyvary, I desire to emphasize the fact that various minor changes indetails of construction, proportion and arrangement of parts may beresorted to, when required, without sacrificing any of the advantages ofmy invention, as set forth. 4

hat is claimed is A cattle guard consisting of a guard element to bepivoted adjacent to one of the cross ties of a railway track and beingnormally in down position, below the level of the top of the rails ofthe track, an operating member pivoted at one end to said guard elementat a point intermediate the ends of said guard element, a pivot rodextending through the other end of said operating member, longitudinallyslotted guide blocks adapted to be secured to an adjacent cross tie andslide blocks secured to the ends of said pivot rod and being slidablymounted within said guide blocks.

In testimony whereof I aiiix my signature in presence of two Witnesses.
